Description
Technical field
The present invention relates to pulse firing (firing) pattern of transformator for calculating electrostatic precipitator method and
Electrostatic precipitator.
Such as, electrostatic precipitator belongs to the type used in power plant or commercial Application.There is less electrostatic precipitator
Other application be possible in a word.
Background technology
Known electrostatic precipitator includes being connected to transformator and then being connected to the filter of commutator.Generally, transformator and
Commutator is embedded in an individual unit.Filter is connected to power supply, such as, arrive electrical network；Commutator so be connected to collection
Electrode and sparking electrode.
During operation, commutator receives electrical power from electrical network (such as, this electrical power can have sinusoidal voltage and electric current
Process (course)) and according to some half-waves of pulse firing mode skipping electrical power (such as, voltage or electric current), thus raw
Become to be supplied to the pulsating power of transformator.
Pulse firing pattern is the first element of the pulse of instruction main points fire and instruction is not lighted a fire second yuan of pulse
The sequence of element.Pulse firing pattern is defined to pulse period or pulse firing modal length, and it has first element and idol
Several second elements；Pulse period thus there is odd number element.
If transformator is supplied with the pulsation merit of two or more continuous impulses with identical polar (that is, plus or minus)
Rate, this will cause the risk that transformator is saturated.Due to this reason, conventionally used pulse firing pattern has one first
Element and even number the second element.
It addition, the most only carry out the supply of pulsating power so that the power being sent to colelctor electrode and sparking electrode is adapted to
The character (such as, in terms of resistivity) of waste gas, and carry out energy management by the amplitude of regulation pulse and (be sent to regulation
Colelctor electrode and the power of sparking electrode).
But, because use pulse firing pattern time from electrical network more only rather than whole power is supplied
To colelctor electrode and sparking electrode, pulse firing pattern supply on restriction is to colelctor electrode and the power of sparking electrode.
Fig. 1,2a, 2b, 3a, 3b illustrate voltage or the electric current being supplied to transformator.
Fig. 1 is shown in feelings when not applying pulse firing pattern and all power from electrical network to be supplied to transformator
Condition.Especially, it is supplied to the voltage of filter or electric current with reference to 1 mark from electrical network and is supplied to from filter with reference to 2 marks
The voltage of transformator or electric current.In this case, 100% power from electrical network is supplied to transformator and thus is supplied to
Colelctor electrode and sparking electrode.
Fig. 2 a is shown in the pulse firing pattern of application drawing 2b at filter and only 1/3 power from electrical network is turned
Deliver to transformator and from 2/3 power of electrical network at filter, be blocked and be not supplied to transformator time situation.Equally
In this case, it is supplied to the voltage of filter or electric current with reference to 1 mark from electrical network and is supplied to from filter with reference to 2 marks
The voltage of transformator or electric current.Curly brackets 3 marker pulses cycle or pulse firing modal length.In this case, from electricity
33% power of net is supplied to transformator and thus is supplied to colelctor electrode and sparking electrode.

And from 4/5 power of electrical network at filter, be blocked and be not supplied to transformator time situation.The most in this case,
Be supplied to voltage or the electric current of filter from electrical network with reference to 1 mark, with reference to 2 marks from filter be supplied to transformator voltage or
Electric current and curly brackets 3 marker pulses cycle or pulse firing modal length.In this case, from 20% power of electrical network
It is supplied to transformator and thus is supplied to colelctor electrode and sparking electrode.
Allow to colelctor electrode and sparking electrode supply peak power pulse firing pattern use (Fig. 2 a, 2b) with do not make
With the step (step) between pulse firing pattern (Fig. 1) corresponding to 67% power from electrical network supply, this thus be obvious.
This big power steps can not allow optimal performance because only processed gas feature allow only with from
In the case of colelctor electrode and sparking electrode are supplied by 33% power of electrical network supply, it is possible for using pulse firing pattern；If
From electrical network 33% power use in view of the feature of processed gas but impossible, need there is no pulse firing mould
The operation of formula.In other words, if the feature of gas can require to use corresponding to such as from the pulse point of 50% power of electrical network
Fire pattern, the operation using pulse firing pattern is impossible, because since the use of pulse firing pattern will only allow
From 33% power of electrical network to colelctor electrode and sparking electrode supply.Thus the operation not having pulse firing pattern will be may require that.
It addition, as carried out traditionally, reduce, via (voltage and/or electric current) amplitude, the power adjustments shadow made
Ring the corona discharge from sparking electrode and thus negative effect Dust charge (its via corona occur) and therefore affecting
Dust at colelctor electrode is collected.
